HELP!!

[Jsabe07]

I need help with my furnace!! I'm in the middle of camping in Ohio and it's going to get cold tonight. I tried my furnace this afternoon on my 371 REBH and it lights for about 5-8 seconds and then goes out. It does this cycle 3 times, and then cools and shuts off. I can't even get to the furnace compartment, so I don't know what to do!!!! Help!!

I'm not familiar with your trailer so I don't know how to access the furnace.

If its an Atwood furnace the circuit board will flash the error codes.

Attached is a file I have that might help.

The question that has to be asked, are you sure you have plenty of propane? Do the burners on your stove work?

Next question, is there anything obstructing the furnace vent outside? Look in it with a bright light. Any insects build a nest.

When did it work last?

To answer your questions, I had the propane filled before we left. I put a flashlight in the vents and I saw and cleared a mud dauber nest. And the last time we really used it was in the spring after we first bought it

The mud dauber nest may go farther up. I would also shut off and turn on your propane and check its connections. Run the stove a bit. you may have air in the lines. In the meantime, if you have the fireplace option, use that to help heat your trailer.

Candidate for furnace vent screen.

Worst case for now if all the above fails, get a portable space heater, or 2. Heck most of the time that's what we use anyway to save the propane. That is, provided it's not just stupid cold.

May be want to get out to Walmart for a space heater till this is resolved.

[Evereddie]

If you turn your propane tank off to bleed your lines, when you turn it back on, do it very slowly. If you turn it on too fast the auto cutoff valve will think it is a sudden leak and cutoff the propane flow.

I had the exact problem with my 2014 Sandpiper 385 FKBH last season and at the beginning of this season. If you have propane there are only two things that can be wrong; either the thermocouple or the circuit board. The thermocouple detects whether you have flame after the ignition sequence. If no flame is detected it shuts off the propane and the furnace. If the circuit card is the problem you get the same indications. The only way the tech investigating mine could determine the fault was to remove the furnace and replace one component at a time until it ran properly and produced heat.

And that's what the guy told me once we got back into town and I took it to be winterized.

I had the same problem and had to pull the furnace and clean the exhaust. The dirt dobbers plugged it up with their nest. Once cleaned she ran perfectly. Bought an exhaust screen to fix the problem.
